“…The TABLE II [1] can be explained by the use of patch antennas, different bandwidths and different transmit powers. The results prove that due to the wave guide effect, the 70 m channel can attain, with less transmit power, the same capacity as the 40 m channel.…”

This letter studies the performance of the line-ofsight underground mine channel in the millimeter wave band. Using a vector network analyzer (VNA) and three carefully chosen antennas, one omni and two horn antennas, we performed measurements at the 40 and 70 m levels in the CANMET mine located in Val-d'Or, Canada. The performance of the channel is studied in terms of its path loss exponent, shadowing and capacity. Results prove that the path loss exponent in an underground mine is smaller than the free space value. The shadow fading fits very well with the normal distribution. A model of the capacity as a function of the distance between transmitter and receiver is investigated. Channel capacity depends on the multipath characteristics; the capacity found in the narrow environment (70 m) is higher than in the wider environment (40 m). The results also show that it is better to use omnidirectional antennas for a wireless communication system in the millimeter wave band in an underground mine environment.

“…Among the techniques that are proposed, the increase in frequency to the millimeter wave (mmW) spectrum is a promising way to meet this need for broadband communications [1], [2]. Millimeter wave systems appeared about twenty years ago as a promising solution for new types of wireless networks.…”

“…This method is useful to investigate the multipath richness of the environment, and is suitable for the scenario where the transmitted power can compensate for the total received power variation in each receive element [18]. However, this normalization removes any power variation of the measurement path and thus the changes in the path loss in different propagation scenarios are not included, which can be called the relative path loss (RPL).…”

In this paper, a co-located tri-polarized loop (TPL) antenna is proposed and a co-located tri-polarized dipole (TPD) antenna is also designed for multiple-input multiple-output (MIMO) performance comparison. Both antennas have satisfactory performances of impedance bandwidth and isolation. The channel measurements are conducted in a non-lossy reverberation chamber (RC), a lossy RC, a corridor and an office room. For both antennas, the measured average correlation coefficients (CCs) in the non-lossy RC are the smallest, close to 0.1, in the lossy RC are the largest, 0.3-0.5, and in the two indoor scenarios are slightly larger than that in the non-lossy RC. Except for the signal correlation, the relative path loss (RPL) should also be included to fairly compare the channel capacities. If the RPL is considered, a strong dependence of the channel capacity on the propagation properties can be seen. For both antennas, the channel capacities in the two indoor scenarios are 20%-30% smaller than that in the non-lossy RC. Interestingly, both antennas have similar condition numbers (CNs) in all the four scenarios, whose PDFs are close to that of the independent identically distributed (i.i.d) complex Gaussian channel, which reveals that both antennas can obtain nearly three independent parallel subchannels and good multiplexing performance.Index Terms-Tri-polarized loop (TPL), tri-polarized dipole (TPD), multiple-input multiple-output (MIMO), measurement. 0018-926X (c)

A novel printed 60-GHz antenna for MIMO/diversity applications is presented in this paper. This antenna consists of two coplanar waveguides (CPW) feeding triangle-shaped radiating element for orthogonal radiation pattern and a rectangle stub is inserted at 45°between them to achieve high isolation. The antenna is prototyped using RO5880 printed-circuit board. Experimental result shows that the antenna impedance bandwidth for S11<-10dB is 54.5GHz to 63.1 GHz including the majority 60-GHz working band. The compact size of 5.5mm*5.5mm indicates that the proposed antenna is a candidate for mobile WPAN systems.
